_F_o_r_m_a_t:

     This data frame contains the following columns:

     _d_e_l_t_a_B_P a numeric vector

     _d_o_s_e a numeric vector

     _R_u_n an ordered factor with levels 'T5' < 'T4' < 'T3' < 'T2' < 'T1'
          < 'P5' < 'P3' < 'P2' < 'P4' < 'P1'

     _T_r_e_a_t_m_e_n_t a factor with levels 'MDL 72222'  'Placebo' 

     _R_a_b_b_i_t an ordered factor with levels '5' < '3' < '2' < '4' < '1'

_D_e_t_a_i_l_s:

     Data on an experiment to examine the effect of a antagonist MDL
     72222 on the change in blood pressure experienced with increasing
     dosage of phenylbiguanide are described in Ludbrook (1994) and
     analyzed in Venables and Ripley (1999, section 8.8).  Each of five
     rabbits was exposed to increasing doses of phenylbiguanide after
     having either a placebo or the HD5-antagonist MDL 72222
     administered.
